just ran a couple tests, my sabre without battery is 19.3 oz, with battery 24.5, I had the CG perfect in flight. exceed motor pulled 211 W at 18 Amps, very similar to my hacker a20-20l, just no where near as smooth, I'm thinking I need around 250W

You're still pulling around 140 watts per pound. Not that bad. But some more might be nice.

If you're not using it, the 20/20L is a good motor for it--that's what I have in mine. Was a little worried, as I have a Hacker 20A ESC, and I pull about 22-23A with an APC 10x3.8, but have literally hundreds of flights on it now with no issues.

A few amps over wont hurt .. that's a WOT with fresh pack. How much time do you spend @ WOT with this plane? Not much.
I've been flying a eflite 450 11x3.8 and Thunderbird 18 for years no issues .. it pulls 23amp burst.

I'm currently trying out a smaller 2215 920 with a smaller 10x3.8 .. seems a bit more snappy, a bit lighter combo as well .. which always help. Spaz recommends a slight higher kv than I've used so I ordered a MotroFly 2215 1150kv. I never heard or used this brand until I bought one for my 60" extreme flight edge. They aint cheap but very impressive performance and quality.
I posted a pic of the business end of my Edge motor and the stats on the motor for the 2215 1150kv FYI.

the 20/20L is pretty happy right now on the 38" slick, I might order the motorfly 2215-1150 to try, but it is rated at 188W which still seems at little low. ALso looking at MicroDan 2510-1300 but not sure this might be to high of a KV

I may have to reconcicder using the axi 2212 26 but I figure it will be easy to CG, I can amp it up without it getting hot, and its a tried and true set up for my foamies below 25oz on 3s 1000 and 10x4.7...
opinions on this motor setup are welcome?

I have the axi, but not the hacker right now.

Just finishing mine up. Seems like a really nice plane with a straight forward build. I'm looking forward to flying it.

E400 motor
CC Phoenix 25
GWS 1060DD prop
HS 65 tail
HS 55 ailerons
Battery - start with TP 1320 and will probably order 1500's

The push-rods are super light but very flexible. I hate to add weight. Any suggestions? Maybe carbon tube over the rods?

I threw those out, bend like crazy. I used some tail servo push rods I had from previous trex 250/450 builds, not much heavier, but much stronger

Let us know how the e400 does, I'm tempted to just order one, but would prefer the e450

I think the 1320 will be fine, I flew with gens ace 1300 and 1800 today and both flew great, a little floatier with the 1300

For the rods I like using 1/32 wire for z bends on the surface side then .062" carbon for the rest, held on with shrink tubing, then thin ca to lock it on, the carbon rod will fit in the included ez connector
